If you are an Ontario Health Study participant, time is running out to complete the Study’s first Follow-up Questionnaire before it closes March 31. By taking part in the questionnaire, which takes 30 minutes to complete, participants provide an update on their health that can be compared against data from the Study’s initial questionnaire. Scientists will be able to use the data that is gathered and compare data between the two questionnaires to study how lifestyle, environment and family history affect health over time and to develop strategies for the prevention, early detection and treatment of diseases.

The OHS is part a nationwide research platform called the Canadian Partnership for Tomorrow Project that has obtained health data from more than 300,000 Canadians — nearly one in every 50 individuals between the ages of 35-69.

Since the Follow-up Questionnaire was launched in November of 2016, more than 40,000 Study participants have competed or begun the process of completing it. The questionnaire seeks information about a person’s health that may have changed since the first time the provided information about to the Study such as height and weight. Participants can also expect to see some new questions, which seek data on mental health, eCigarette and marijuana use, and the use of over-the-counter drugs.
